Mean intensity of infection in different age groupings (A) and the number of years of annual treatment to achieve elimination of T. trichiura with and without Pre-SAC being eligible for ivermectin co-administration (B). The age profile of infection intensity used to parameterise the model (Fig. 1) is taken from (Bundy et al., 1987). ^†Accounting for both the age profile of infection intensity and the assumed demography (Truscott et al., 2014) yields an estimate of 25% of the worms occurring in Pre-SAC. Results in panel B) pertain to a fitted (higher) transmission setting (R₀ = 1.75). Durations over ten years were not considered (marked as NA (not achievable)). ALB; Albendazole, IVM; Ivermectin.
